Verified sending domains to become mandatory

This change affects users of our BoltMail email marketing platform. We will soon be requiring a verified sending domain for all email campaigns. Verified sending domains prevent email spoofing and are required when sending bulk email to major ESPs including Google, Microsoft and Yahoo. Up until now we had been strongly encouraging the use of verified sending domains but this had not been enforced. We now need to begin enforcing sending domains to meet sending requirements and to keep your email campaigns out of spam folders or from being rejected entirely.
If you are not yet using a verified sending domain you need to take action now.
For more information please see: Creating a sending domain
